I wonder what a feature by feature comparison would look like with the commercial cold rb optical clock? https://spectradynamics.com/products/crb-clock/ https://spectradynamics.com/products/crb-clock/ Which is seems to be about 1/5th the size, 1/10th the cost, and maybe 1/100th the long term stability (though the optical lattice clock doesn't have an adev chart, so I'm just comparing 10^-15 with 10^-18). I wonder if the lattice clock can be moved while operating? IIRC the CRB can't, and requires better than 1 degree leveling so the cooled rb cloud can be in freefall.
